Developed on the chassis of the M70 MBT (you can see the rear end is facing forward), this SPG carries twin-gaged 150mm howitzers. The idea behind it is, that two smaller shells hitting at the same time deal more damage than a single big shell. And the coalition is capable of just that: Each gun has a different shell velocity, enabling the shells to hit the target at the same time. The vehicle itself houses the guns in a large superstructure on the opposite end of the chassis, with a large shovel-like-thing so it can dig in it's rear so it doesn't get blown away by the recoil of the guns.
It also looks hella badass.

About this creation

I'd also like to apologise for the weird background of my pictures, the model is simply too big to fit in my little white-paper-studio.
